How can cats see in the dark?

How can cats see in the dark? The answer is that they have a reflective layer behind the retina of the eyes which bounces back light into the eye, onto the retina, boosting the reception of the light. You can see this reflective layer on occasions when a light is shone into the eyes of a cat. It is noticeable at night when driving, if and when you see a cat looking towards you. The car lights are reflected in the eyes of the cat and you see this green, sharp glow-"cat's eyes". Cats have developed this in order to hunt more effectively at dawn and at dusk or during the night. It is an evolved anatomical development of the eye to improve survival. It is Darwin's survival of the fittest in action. This evolutionary development took place in the North African wild cat, the ancient wild ancestor of our beloved domestic cat.
